Introduction

Wine is an alcoholic beverage produced through the partial or total fermentation of

grapes. Other fruits and plants, such as berries, apples, cherries, dandelions, elder-

berries, palm, and rice can also be fermented. The theory that wine was discovered by

accident is most likely correct because wine grapes contain all the necessary

ingredients for wine, including pulp, juice, and seeds that possess all the acids, sugars,

tannins, minerals, and vitamins that are found in wine. As a natural process, the frosty-

looking skin of the grape, called "bloom," catches the airborne yeast and enzymes that

ferment the juice of the grape into wine.


Significance of wine making

Wine has undoubtedly had significant economic and social impacts. Today, wine

production has spread worldwide with hotspots on five continents including France, the

United States, South Africa, Chile, and Australia. Agricultural industries like wine

production can have profound effects on the vitality of the natural landscape. The sheer

geographic span of the wine industry makes it a particularly interesting case for

investigation within an environmental context. Specifically, an analysis of the use of

market-based mechanisms in the wine industry is important for devising management

strategies that can promote environmental conservation alongside economic prosperity.

Questions:

1. Write all the chemical reaction involve in the fermentation process.

Production of ethanol from glucose net chemical equation is: C6H12O6 (glucose) → 2
C2H5OH (ethanol) + 2 CO2 (carbon dioxide). This type of fermentation is used for the
production of wine or beer.

2. Why is it that oftentimes the cotton you use to cover the mouth of the bottle is
thrown upward?
